Increasing use of e-government has raised issues about the privacy of information provided by citizens to government. This paper explores the experiences and concerns of New Zealanders in relation to information privacy, and the impact of these concerns on the trust they place in government. A series of focus groups were conducted among a range of community groups. The findings reflect a range of attitudes about information privacy and the trustworthiness of government, and centre around two major themes: the use of technology and concerns about the competency of and practices of government employees. Most respondents were unaware of their existing protections; preferred face to face communication; had low levels of confidence in the privacy of online communication but made use of it for convenience sake; had greater confidence in government than in commercial organizations but made distinctions between individual agencies. Breaches of privacy were shown to have a negative impact on trust in government.
Effective space utilization is an important consideration in logistics systems and is especially important in dense storage environments. Dense storage systems provide high-space utilization; however, because not all items are immediately accessible, storage and retrieval operations often require shifting of other stored items in order to access the desired item, which results in item location uncertainty when asset tracking is insufficient. Given an initial certainty in item location, we use Markovian principles to quantify the growth of uncertainty as a function of retrieval requests and discover that the steady state probability distribution for any communicating class of storage locations approaches uniform. Using this result, an expected search time model is developed and applied to the systems analyzed. We also develop metrics that quantify and characterize uncertainty in item location to aid in understanding the nature of that uncertainty. By incorporating uncertainty into our logistics model and conducting numerical experiments, we gain valuable insights into the uncertainty problem such as the benefit of multiple item copies in reducing expected search time and the varied response to different retrieval policies in otherwise identical systems. v TABLE OF CONTENTS LIST OF FIGURES .

Liquid Metals were used to make sliding electric contacts by Michael Faraday, in 1832. In contrast to solid sliding electric contacts, liquid metals provide uniform coverage to a moving surface and therefore have very low electrical contact losses and are essentially wear free. However, being liquid, the contacts are subject to hydrodynamic instabilities which can cause the liquid to leave the electric contact region and therefore not function. Theoretical considerations suggest these instabilities can become worse at large diameters (1-2 meters). This paper describes an apparatus that was designed to investigate the operation of liquid metal sliding electrical contacts in large magnetic fields. The apparatus consist of a large diameter sliding contact surface rotated by an external drive motor and connected to a direct current power supply of 100,000 amps. The sliding contact apparatus sits in a background magnetic field of up to 2T which can be arbitrarily oriented by changing the current in a superconductive magnet system with a novel dipole-quadrupole configuration. Preliminary data are presented on operation of the test apparatus with liquid metal filled fibers. The Slipring resistance was between 0.1 and 0.2 micro-ohms. Circulating current losses were measured near 3kW for a 2.2 T radial magnetic field at 100 rpm while losses in 1.6T axial magnetic fields were around a kW at similar speed. The apparatus was operated for several months and no instabilities were observed in the large diameter collector.
